June 15 - 22 "Batik" Type Resist with Underglazes

Well in one of my posts to Clayart I mentioned all the different techniques that I use, include "batik type resist with underglazes". A clayarter asked me to elaborate so I have included two pictures of 2 plates done a couple of years ago in that method and a brief explanation. They were done in oxidation fired to cone 7 1/2 and sprayed with Stoney White over non-commercial brown and blue underglazes. There is also a bit of overspray with rutile/gerstley borate and rutile/gerstley borate/red iron to give beige and darker beige highlights.

I refer to it as "batik" because you do it backwards as you would batik. First I wax all the areas where I do not want underglaze which is usually most of the pot. Then on the wheel I brush on the first base underglaze. Doing it on the wheel gives you an even coat. You also get little beads of underglaze on the waxed areas that add to the design. The beads kind of are reminiscent of the crackle lines that you get in batik.

I usually use a brown iron underglaze first. Then I wax the areas that I want to keep brown. So then I brush on the blue underglaze. If I wanted a third colour like green, I would wax out the areas that I want to stay blue and then brush on the green etc. I usually just use brown and blue. Now you have to rebisque to burn off the wax. So it is more time consuming but it gives a totally different effect than drawing directly. Try it and you will see what I mean.

I use this technique as I do not have very good drawing skills. I could let's say draw a flower in blue and brown underglaze but it would end up amateurish. By using the "batik" method I draw around the outline of the flower, the leaves, the petals, the stem and somehow that gives a very different effect and takes away some of the need to have good drawing skills - it adds a bit of naivety and simplicity. Not sure if that makes sense. In the 70's and 80's I guess that was my style, trying for a reduction look in electric. As I now have use of a gas kiln I no longer use this as much, though I am trying to find a glaze for cone 10 redux that would work with underglazes like the Stoney White.

About Me

In Dec 2009 I renamed my first blog to Centered - Focus on Clay and Creativity - as I have finished my year long journey workshop with Steven Hill. The focus will continue to be on thoughts about my work - about creativity, design and function...................
I have been making pottery off and on for 40 years, exploring many different aspects of ceramics. I named my pottery business after "The Newfoundout" - the secluded valley high in the Opeongo Hills of eastern Ontario where we own an abandoned farm and where in 2007 I built a wood-fired kiln. I normally fire in a gas kiln in Deep River, Ontario, at the Deep River Potters' Guild, but do several wood firings in the summer.
This blog originally documented my year long "journey workshop" with Steven Hill. It was an incredible "journey" which had a profound effect on my work and as was the North Bay mentorship. I highly recommend this type of workshop to anyone who is interested in exploring their work and creativity.
